versionutil的Python项目详细描述
比较python系统版本的便利函数
安装
从项目根目录:
$ python setup.py install
用法
提供比较python版本,以便您可以检查主版本、次版本和微版本:
from versionutil import compare_python, PYTHON # compare_python will return a boolean value against the current system version. # PYTHON represents an instance of an object that is the current system version. # It will check at the most significant value you signify. Default is equality check. # True using 2.7.9: PYTHON == '2' PYTHON == '2.7' PYTHON == '2.7.9' compare_python('2') compare_python('2.7') compare_python('2.7.9') # True using 3.4.4: PYTHON == '3' PYTHON == '3.4' PYTHON == '3.4.4' compare_python('3') compare_python('3.4') compare_python('3.4.4') # False in 3.4.4: PYTHON != '3.5' PYTHON != '3.4.5' compare_python('3.5') compare_python('3.4.5') # Works with ints and even floats: PYTHON == 2.7 compare_python(2.7) # Different comparisons exist, default comp='==' PYTHON != 3 PYTHON < 3 PYTHON < 3.0 PYTHON > 2.6 PYTHON >= 2.7 PYTHON < 3.1 compare_python(3, '!=') compare_python(3, '<') compare_python(3.0, '<') compare_python(2.6, '>') compare_python(2.7, '>=') compare_python(3.1, comp='<') # To test against a custom system version (ignore sys.version_info): compare_python(5.4, sysv=(5, 4, 5)) # or to create a PYTHON like object for 5.4.5: from versionutil import PythonVersion pv545 = PythonVersion(sysv=(5, 4, 5)) if pv545 == 5.4: # True... # Useful for handling imports, where otherwise pyfuture and pasteurize might not have what you need. if PYTHON < 3: from oldapi import OldAPI as API elif PYTHON == 3.0 or PYTHON == 3.1: from newapi import OtherAPI as API elif PYTHON >= 3.2: from newapi import NewAPI as API
